Doritaenopsis plant named ‘SOGO F1016’

ABSTRACT

A new and distinct cultivar of  Doritaenopsis  plant named ‘SOGO F1016’, characterized by its flowers of yellow overlaid toward white base and the white with red labellum, freely flowering habit, upright, freely branching and sturdy flowering stems, and the excellent postproduction longevity.

FIELD OF THE INVENTION

Botanical classification/cultivar designation: Doritaenopsis Orchidcultivar SOGO F1016.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar ofDoritaenopsis Orchid, a bigeneric hybrid of Doritis.times.Phalaenopsisof the family Orchidaceae, and hereinafter referred to by a cultivarname, ‘SOGO F1016’. The genus Doritaenopsis is a member of the familyOrchidaceae.

Doritaenopsis comprise a group of bigeneric hybrids generallyintermediate in character between the parent genera, which are suitablefor cultivation in the home or greenhouse. The parent genera ofDoritaenopsis are predominantly epiphytic or rock dwelling, and arenative to tropical Asia, Malay Archipelago, and Oceania. The speciestypically have 2-ranked fleshy oblong or elliptic leaves affixed to ashort central stem (monopodial growth), which vary in size from 5 to 8inches to over 2 feet. The leaves may be entirely green or mottled withsilver grey.

Doritaenopsis orchid, often referred to Moth Orchids in thehorticultural trade, are frequently used to furnish cut flowers for theflorist trade, or sold as flowering potted plants for home orinteriorscape.

Doritaenopsis produce upright racemes, often with many showy flowers,which open in succession beginning with the lowermost. The flowerspossess three sepals, and three petals, the lateral ones being alike.The lowermost petal, called the labellum, is three lobed and is oftenmore brightly colored than other flower segments. Flower colors arefrequently various shades of pink, white and yellow.

Doritaenopsis orchids are typically propagated from seeds. However,Doritaenopsis is capable of being asexually reproduced from offshoots,which frequently arise from the lower bracts of the inflorescence. Theresulting plants are detached from the mother plant and may be plantedin a suitable substrate.

‘SOGO F1016’ is a product of a planned breeding program conducted by theinventor in Kaohsiung County, Taiwan, R.O.C. The objective of thebreeding program is to create new uniform pot-type Doritaenopsis Orchidcultivars having attractive flower coloration. The inventor has beenaddressed himself to the Orchids breeding since 1985.

‘SOGO F1016’ was discovered by the inventor from within the progeny of across-pollination of one Phalaenopsis Orchid and one DoritaenopsisOrchid on Feb. 1999, in a controlled environment in Kaohsiung County,Taiwan, R.O.C.

Asexual propagation by tissue culture in a laboratory in PingdongCounty, Taiwan, R.O.C. has been used to increase the number of plantsfor evaluation and has demonstrated in a controlled environment inKaohsiung County, Taiwan, R.O.C. that the unique combination ofcharacteristics as herein disclosed for the new Doritaenopsis Orchid arefirmly fixed and are retained through successive generations of asexualreproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined tobe basic characteristics of ‘SOGO F1016’ which in combinationdistinguish this Doritaenopsis Orchid as a new and distinct cultivar:

-   -   1. Yellow overlaid toward white base and the white with red        colored labellum.    -   2. Freely flowering habit.    -   3. Upright, freely branching and sturdy flowering stems.    -   4. Excellent postproduction longevity.

Plants of ‘SOGO F1016’ differ primarily from plants of parent cultivarsin flower color.

Currently, there is no commercial cultivar to which ‘SOGO F1016’ can bemeaningfully compared.
